You will need a 300mmx300mm print bed to print the split portions. I have provided the Inkscape SVG project file in case you want to slice it up to whatever you want. There's also a full STL if you want to cut it in PrusaSlicer.
Suggestions:
My photo is of the one with 2.0mm lines using a 0.8mm nozzle. It is pre-assembly and painting (obviously)
I sketched it in Onshape, exported the .dxf into Inkscape, then exported a plain .svg. I then used svg2stl.com to create a 3mm thick .stl file. I split the model in PrusaSlicer.
